- Added support for 13 new syscalls to allow more things to compile when using uClibc. mincore() and the ones for Extended Attributes setxattr(), lsetxattr(), fsetxattr(), getxattr(), lgetxattr(), fgetxattr(), listxattr(), llistxattr(), flistxattr(), removexattr(), lremovexattr(), fremovexattr() which are optional.
